cab drivers have to take quarters for payment
a quarter is legal tender
if you had a $50 cab fare and wanted to pay in pennies the cabbie is legally required to take it
if a cab driver ever tells you that again tell him you are calling the police and see what he thinks about your quarters then

hey, i was a cabbie and i would take quarters. money is money and sometimes that's all they had. who am i to judge? and i don't mind when people pay in change. except i have to count it, people are too sloooooooooow
